321 Stainless Steel Sheet/Plate Suppliers

321 stainless steel sheet is part of the austenitic stainless steel family. 321 is basically a 304 grade containing titanium stabilizers. 321 type is ideal for applications where heat is a concern. 321 can be used for applications up to 900°C, while 304 is typically used up to 500°C. 321 grade has excellent forming and welding characteristics. It does not polish well and therefore will not be used in decorative applications.TW stocks a variety of sizes of 321 stainless steel, certified to AMS 5510, ASTM A 240 and SA 666.

321 stainless steel sheet is commonly used in aerospace, thermal, electrical, and structural applications. 321 stainless steel is reinforced with titanium, an alloy that performs well in high-temperature environments and is resistant to cracking and corrosion. 321 sheet/plate stock is available in full size and custom-cut lengths. We produce 321 stainless steel sheets to specifications such as AMS 5510 and ASTM A240 and can customize all thicknesses, sizes, and dimensions.

Surface   finish Characteristics & Application
NO.1 Hot-rolled   surface,annealed and pickled,can be used as cold-rolling material,industial   tanks and chem i cal devices.
NO.2D Cold-rolled,   an nealed and pick led with out skinpassing the dull products can be used as   automobile parts, building materrials and pipings.
NO.2B The   surface brightness and flatness of NO.2B is better than NO.2D. Then through a   special  surfacetreament to improve its mechamical properties, N02B   could nearly satisfy comprehensive uses.
NO.3 Polished   with abra sive belt of grit #100#120,have bet ter bright ness with   discontinuous coarse stria, used as in ner and ex ter nal or na ments for   building, electrical appliances and kitchen uten sils etc.
NO.4 Polished   with abrasive belt of grit #150#180, have better brightness with   discontinuous coarse stria, but thinner than NO.3, are used as bathtud   buildinginner and external ornaments electrical appliances, kitchen utensils   and food processing equipment etc.
HL Polished   with abrasive belt of grit #150-320 on the No.4 finish and has continuous   streaks,  mainly used as building ornaments, elevators, door of   building, frontal plate etc.
BA Cold   rolled, bright annealed and skin passed, the product has excellent brightness   and good reflexivity like mirror, used for lectrical appliances, mirror,   kitchen apparatus, or nament materials etc.
